Hello all...I am trying to disable output from the openfoam solver, and use a writeRegisteredObject function in the controlDict to only output one field (p). I am doing this because I don't need the rest, and it's taking up too much memory.

I have pasted my controlDict below...I have changed my writeinterval to a very large value to disable solver output, and included the function however I am not getting any output at all now when I run the solver?

Anyone have an idea what I can change? I want to output the results of p every 0.05s

libIOFunctionObjects is deprecated.
Use:

Code:
functions
{
  writeOptional
    {
        type        writeObjects;
        libs        ("libutilityFunctionObjects.so");
        writeControl    timeStep;
        writeInterval   1;
        objects     (U);
    }
}
